Do not expand cube set

[Chance1234]

I have the following two lines

sb.Append("<script>document.all.pTable.ActiveView.RowAxis.InsertFieldSet(document.all.pTable.ActiveView.fieldsets('[service_name]'))</
script>");
sb.Append("<script>document.all.pTable.ActiveView.RowAxis.Fieldsets('[service_name]').fields('[service_name]').expanded
= false)</script>");

service_name is a cube field and i dont want to display the lower
parts of the cube, I have tried ddifferent combinations of syntax,
but cant find where the cube "sits"
